North West -- Off the Chain Cuteness (PHOTO)

Let there be no doubt ... Kanye West has the most adorable chick in the game wearing his chain -- as 'Hova once put it.

North West stepped out with Mom Monday in NYC but her outfit -- complete with combat boots and a fat gold chain -- was clearly an homage to Dad, who frequently rocks the exact same look ... in adult sizes.

Whether she's copying Kanye or Kim Kardashian ... North has learned to work the mini-me thing for all it's worth.
